That is really nice.
I think a profile is a good idea. As soon as I saw the first pic I thought, "I've seen this fish before". Possibly on "the other forum"
Jim, these chaps are very visible. Not skittish or shy at all. They seem to spend most of the time grazing on pebbles and searching for food on the substrate. I see them the odd time on the glass. I also haven't seen any aggression to-wards the other occupants.
